Abstract
This research was conducted on April 2013. Sampel of sea water and sediment were taken fromPangke Bay waters Karimun Regency, Riau Archipelago. Analysis of heavy metal concentration was carried out in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science, University of Riau by using an Atomic Absortion Spectrophotometer Perkin Elmer 3110. The results showed that highest consentration of Pb and Zn insea water was found in around PT. Saipem Indonesia waters (0,0623 mg/L and 0,4937 mg/L) and concentration of Cu was highest in PT. Pacific Granita port (0,0390 mg/L). Whilst the highest concentration of Pb was found in around PT. Saipem Indonesia waters (8,6333µg/g), Cu in anthropogenic activities area (2,5766 µg/g) and Zn in PT. Pacific Granita port (8,8500 µg/g).The lowest concentration of Pb, Cu and Zn was found in station nearby mangrove area and far from industrial activities (0,0487, 0,0146 and 0,0397 mg/L for sea water and 3,3500, 0,6183 and 5,8000 μg/g for sediment) for Pb,Cu and Zn respectively. Concentrations of Pb, Cu and Zn in sediment of Pangke Bay were still lower than ERL and ERM values which can be concluded that Pangke Bay waters does not have negative impact to organisms living in the surrounding area.
